One issue was that we didn't have control of the throttle. We still needed a crimp on the cable to connect to the valve, hence we opted to turn the idle way up (idle is good for 1.4 hp
).
I'm surprised still that we didn't shear off any of those teeth on the clutch... only 2 8-32 bolts holding each tooth on. And only one tooth actually provides the torque (the teeth are about 175 degrees apart).
Today I went back to the school and took some photos of the other side of the car that has more logos. I also weighed the car, and it came in at 116.4 lbs, which is about 15 lbs heavier than I wanted. Only the cooled seat, batteries, switches, computer, and seat belt remain to be added. I predict a final weights of 123-125 lbs.
Making an 80 lb car is going to be tough next year.... ~ 20lbs less carbon fiber and glue, 10 lbs less Bondo, lighter starter motor, smaller batteries, lighter seat and no cooled seat, lighter computer(it weighs a few pounds), thinner windows, milled engine, maybe carbon fiber rims and steering handle, carbon fiber steering, aluminum bolts (with shear calculations), titanium axles (the old car had these), and a lighter big sprocket (hopefully I can get my workplace to wire EDM me a custom one for a Gates carbon fiber timing belt).
I believe the PAC CAR II only weighed 59 lbs... Within our rules, we would be lucky to hit 70lbs with a million bucks... they probably spent more.
I sure hope someone can come up with carbon fiber based radial tires
Maybe rate for 300 psi... they make air tanks out of it for 10,000 psi.
